In Windows with Japanese language setting, Inkscape 1.3.2 freezes when importing a PDF

Summary:

• When importing a PDF in Inkscape 1.3.2, it freezes.
• This bug occurred only on Windows with the Japanese language setting.
  • This language setting is not for Inkscape UI; it is for the Windows OS.

Steps to reproduce:

• Set the language settings of Windows to Japanese
• Open Inkscape
• Drag & drop a PDF to Inkscape
  • I used the attached PDF test.pdf.
• Click the OK button of the dialog
• At this time, Inkscape freezes

What happened?

• To investigate the cause, I built Inkscape and did some experiments in my environment.
• As a result, I found that the function parserIntRange used here freezes.
• However, I could not determine the cause of the bug and why it depends on Windows's language settings.

What should have happened?

• The function parserIntRange should immediately return the appropriate value.
  • In the case of the attached PDF, the value would be std::set<unsigned int>({1}).
  • In fact, when I hard-coded to that value, Inkscape worked fine.
